It is easy if you can figure out how it works. First you take thumb lever and push it counter clockwise with loading slot facing you.(Bullet-like guide insert show you the way to point it.) Second,slide bullet into space provided. Third, pull lever down to push bullet to top of of magazine. These simple steps must be repeated every time for all 75 rounds, so expect your left thumb to get real sore, because the Russian design team put the curve the wrong way and the tab is to small. The bullets do come out real fast but the loading time is a little long in comparision to the Chicom ones. Also you can not store the ammo in this one either.Remember I was the one askin' on how to load this one, but I figured it out on my own while whatchin' WWE RAW last night. I also loaded up a 100 rd. and three 75rd. Chicom drums also. My opinion is the Chinese ones for Store "n" Shoot and the Russian "NEW" one for plinkin'. Gone Postal
